Adding shielding to existing cables

So I have some interconnects that are picking up all sorts of RFi. I know this for two reasons, one, as I move them around the noisy/buzz sound changes, and two, when I switch them out for shielded interconnects the noise goes away.

so, I bought some tinned copper shielding and some new RCA plugs. I’m going to cut the existing RCA plugs off the existing cable and install the new shielding and new plugs. The thing is the new plugs have a plastic body so there is nowhere to easily connect the shielding to ground.

I was thinking of running a pigtail from the shielding and attachIng an eyelet to ground it to my preamp since there is a grounding lug. Would this work or is there a better way given what I intend to use?

Just stumbled across John Darko’s recent vlog on experts vs neophyte view points that has relevance to this thread. Maybe.

Any time I've tried shielded and non shielded varieties of even the same cable....shielded always sounds "closed in" in comparison.

I have ditched mega-dollar cables in my system for williewonka DIY Helix design cables and love them; I can tell you from listening and evaluating over 20+ brands of cables with some retailing for $5K, this DIY Helix beats them all with a build cost of $200...

All of my signal cables are the DIY Helix Typology and Steve has offered the audiophile community a world-class cable at an entry level price which is quite amazing IMHO.

No need to knock it if you haven’t tried it and for $200...

It's a pretty bad idea.
If you don't want to buy a new RCA shielded cable, and you wanna have some fun the only advice I would give you is to paint the whole cables and connectors with a mix of white glue and tourmaline powder.
Just remember that the process will be irreversible.
But honestly, I would opt for a new shielded RCA cable.

As John Darko recommends, I'll listen to the experts first before I lean on my own understanding!
